I did this on my 930 case. I wasn't smart enough to notice that I could just match the other web, so in some places I just kept grinding until I had a fit. I used something - can't remember if it was a cut-off wheel or a saw to make the main cut on the thick web, then used the die grinder to finish it off with some contour.

If a guy like me can do it, someone like you with genuine machining skills should have no issues.

I have, or had, some bits of mag case from a tranny which was converted to a jig. I certainly did not set any fires with my Sawzall cutting that case. I should set the torch on one of the bits to see if I can get it to burn. I know powdered magnesium can burn in the atmosphere, and recall reading of a magnesium engine or something in a race car burning after some other disaster put enough heat in the wrong place. Aren't our cases a magnesium/aluminum alloy, maybe less susceptible, though maybe a bit heavier, than a purer magnesium?

But mag 911 cases are machined all the time, so there must either be little danger here (especially if the cuttings are promptly removed?), or simple ways to deal with it. One doesn't hear of our 911 mag bits acting like flares. And even when a 2.7 blows up, you don't hear of the case burning.
